amps: Generate the possible attribute mastery profile

In dcminfo: Information Matrix for Diagnostic Classification Models

Description

This function is used to generate the possible attribute mastery profile.

Usage

amps(q_matrix, ind_zero_probs = NULL)

Arguments

q_matrix	A J \times K matrix (Q-matrix) defines which attributes are measured by which items.
ind_zero_probs	a vector of integers indicating which attribute mastery profiles have zero probability. The default is NULL (none of the attribute mastery profiles has zero probability).

Value

A matrix giving the generated attribute mastery profiles.
